. Thisinvention relates to 'stripper spindles, and more"v pz irticularlyto the type adapted yfor the stripping of cloth Y Vfrom compressed cottony seed cakes after the-oil has been eX- cakes. 1.

' y themanufacture"of-cotton'seed oil, after the cotton has been'ginned, the seed crushed and the kernels or meats taken out of theV seed 5 tracted "therefrom," or from other compressed Y 10 hull,` -`the ymeats arel ground up and put through a cooking process. Small quantities of the cookedground meats are then wrapped up in a .cloth and placed in a machine in Which'the oil is extracted-by hydraulic pressure. '11n this'proce'ss the cloth is so embedded in the cake' that it is diiiicult of removal. The same difticultyoccurs in linseed oil manufacture, and otherprocesses involving compressing a cake in a clothWrapper.v 20 f' Inorder to strip the cloths mechanically, it has Vbeen proposed tofvvind them upon a spindle. and various spindles for gripping vthejcloth AtoWind it into aroll'have been developed. However tlrewprior spindles have not.k been satisfactory, inasmuch as' thefhoo'ks or' sharp edges employed'for gripping the cloth subject it to such Wear andtearl that these clothsare deteriorated .very rapidly. Vllhejcake cloth itself has involvedaserious problem, and expensive materials .such as camels'hairfarefthe-only. ones that have proved satisfactory. -Hence -rapid deterioration Aof the cake cloth is antexpensive item in theprocess.v v It yisthfereforethe principal vobject of my invention to provide a stripperspindlefor the purpose describedtfvvhichjwill 'operate Witha minimumfamount of mutilation ofthe cake cloth'duringthe stripping process. Ity is a further object of my-inventionto provide' a stripper spindle which -Wi-ll 'permit very simple and rapid insertion of k,thelend of vthe' cloth to be Wound, ofthe Wound'r'oll.

' Referring more particularly to thej drawis illustrated by 'Way of rings, the invention is illustrated as mounted in a machine comprisinga bed 10 supported by frame'members 11 and 12 which are braced by cross members 13. At the rear of the machine a bracket 14 is mounted, carryingupstandingarms 15 and 16 in which are mount-` ed bearings' 17 fand 18. A shaft 19 is jour- 75 naled in the bearingsand carries a fixed pulley 2Q keyed to the shaft and a free pulley 21 adjacent thereto. The pulleys are of the same diameter and a belt 23 driven from a source ofpower, notshovvn, isadapte'd to be'shifted. laterally from one pulley to the other' by means of a belt shifter 24.

The belt shifter comprises a horizontally slidable arm 24 guided in the bracket 14 and carrying upstanding lugs 25 which guide thevbelt 23V therebetween. VThe end ofv the member 24 is pivoted to one arm of a bell crank lever 26 pivoted to the rear trame member 12 as at'27`. The other arm of lthe bell crank lever 26 terminates in an. operating foot pedalBU, which, when depressed, will serve to shift the lever to the keyed pulley` 21'.- `,W'hen the pedal 3() is released, a Weight l 1nn lustratlve of the known mounting and drive for usewith theimprovedspindle, and forms no part of theinvention.

4The stripperV spindle is of hollowconical V formation provided with slotsV in which the endl ofthe cloth may be inserted,to grip it so that thejcloth maybe wound on the spin idle.
